NSK Spherical Roller Bearings 22216EAE4 21316EAKE4 22316EAE4 22217EAE4 High Quality Roller Bearing Origin Japan
NSK Spherical roller bearings have two rows of rollers with a common sphere raceway in the outer ring and two inner ring raceways inclined at an angle to the bearing axis. This gives them an attractive combination of design features making them irreplaceable in many demanding applications. They are self-aligning and consequently insensitive to misalignment of the shaft relative to the housing and to shaft deflection or bending.
